I've wanted this but settled for using dd to copy the start of the disk,
fdisk to rewrite the GPT properly then mdadm to rebuil
Hello,
I have seen some installations with following setup:
GPT
sda1 sdb1 bios_grub md1 0.9
sda2 sdb2 efi md2 0.9
sda3 sdb3 /boot md3 0.9
sda4 sdb4 / md? 1.1
on such installations it's important, that grub installation is made
with "grub-install --removable"
I mean it was some grub bugs about

Yes, i get it. AFAIK,

Not that I know of. An EFI partition needs to be FAT32 or VFAT.
What I think you could do:
Partition the disks with GPT: 2 partitions each, EF

I have toyed with hybrid GPT in the past, in the hope to make an

Hi.
Is there a solution to have a whole-disk RAID (software, mdadm) that is
also partitioned in GPT and bootable in UEFI?
What I imagine:
- RAID1, mirroring: if you ignore the RAID, the data is there.
- The GPT metadata is somewhere not too close to the beginning of the
drive nor too close to
8 matches
